Travel Foreman's "Justice League United" sketchbook has surfaced online, unveiling some of the creator's unused concept artwork for the now-cancelled title's cast of characters. The alternate designs are surprisingly different from earlier designs, and offer a bold alternative to the inevitable costumes that were used for the "Rebirth" rebranding. Foreman worked on "Justice League United" for issues 11, 12 and 16 -- the final issue of the series.
